TECHNICAL FIELD

The present embodiments relate to wireless audio/video recording and communication doorbells.

BACKGROUND

Home safety is a concern for many homeowners and renters. Those seeking to protect or monitor their homes often wish to have video and audio communications with visitors, for example, those visiting an external door or entryway. Audio/Video (A/V) doorbell systems provide this functionality, and can also aid in crime detection and prevention. For example, audio and/or video captured by an A/V doorbell unit can be uploaded to the cloud and recorded on a remote server. Subsequent review of the A/V footage can aid law enforcement in capturing perpetrators of home burglaries and other crimes. Further, the presence of an A/V doorbell unit at the entrance to a home acts as a powerful deterrent against would-be burglars.

Zone 5 is the area that is visible only to Passive Infrared Sensor 144-3. The doorbell 130 may be capable of determining the direction that an object is moving based upon which zones are triggered in a time sequence. In the illustrated embodiment, each zone extends across an angle of 110°. In alternative embodiments, each zone may extend across a different angle, such as one greater than or less than 110°.

FIG. 12 is a functional block diagram of the components within or in communication with the doorbell 130, according to an aspect of the present embodiments. As described above, the bracket PCB 149 may comprise an accelerometer 150, a barometer 151, a humidity sensor 152, and a temperature sensor 153. The accelerometer 150 may be one or more sensors capable of sensing motion and/or acceleration. The barometer 151 may be one or more sensors capable of determining the atmospheric pressure of the surrounding environment in which the bracket PCB 149 may be located. The humidity sensor 152 may be one or more sensors capable of determining the amount of moisture present in the atmospheric environment in which the bracket PCB 149 may be located. The temperature sensor 153 may be one or more sensors capable of determining the temperature of the ambient environment in which the bracket PCB 149 may be located. As described above, the bracket PCB 149 may be located outside the housing of the doorbell 130 so as to reduce interference from heat, pressure, moisture, and/or other stimuli generated by the internal components of the doorbell 130.

With further reference to FIG. 12, the bracket PCB 149 may further comprise terminal screw inserts 154, which may be configured to receive the terminal screws 138 and transmit power to the electrical contacts 177 on the mounting bracket 137 (FIG. 6). The bracket PCB 149 may be electrically and/or mechanically coupled to the power PCB 148 through the terminal screws 138, the terminal screw inserts 154, the spring contacts 140, and the electrical contacts 177. The terminal screws 138 may receive electrical wires located at the surface to which the doorbell 130 is mounted, such as the wall of a building, so that the doorbell can receive electrical power from the building's electrical system. Upon the terminal screws 138 being secured within the terminal screw inserts 154, power may be transferred to the bracket PCB 149, and to all of the components associated therewith, including the electrical contacts 177. The electrical contacts 177 may transfer electrical power to the power PCB 148 by mating with the spring contacts 140.

With further reference to FIG. 12, the front PCB 146 may comprise a light sensor 155, one or more light-emitting components, such as LED's 156, one or more speakers 157, and a microphone 158. The light sensor 155 may be one or more sensors capable of detecting the level of ambient light of the surrounding environment in which the doorbell 130 may be located. LED's 156 may be one or more light-emitting diodes capable of producing visible light when supplied with power. The speakers 157 may be any electromechanical device capable of producing sound in response to an electrical signal input. The microphone 158 may be an acoustic-to-electric transducer or sensor capable of converting sound waves into an electrical signal. When activated, the LED's 156 may illuminate the light pipe 136 (FIG. 2). The front PCB 146 and all components thereof may be electrically coupled to the power PCB 148, thereby allowing data and/or power to be transferred to and from the power PCB 148 and the front PCB 146.

The speakers 157 and the microphone 158 may be coupled to the camera processor 170 through an audio CODEC 161. For example, the transfer of digital audio from the user's client device 114 and the speakers 157 and the microphone 158 may be compressed and decompressed using the audio CODEC 161, coupled to the camera processor 170. Once compressed by audio CODEC 161, digital audio data may be sent through the communication module 164 to the network 112, routed by one or more servers 118, and delivered to the user's client device 114. When the user speaks, after being transferred through the network 112, digital audio data is decompressed by audio CODEC 161 and emitted to the visitor via the speakers 157.

With further reference to FIG. 12, the power PCB 148 may comprise a power management module 162, a microcontroller 163, the communication module 164, and power PCB non-volatile memory 165. In certain embodiments, the power management module 162 may comprise an integrated circuit capable of arbitrating between multiple voltage rails, thereby selecting the source of power for the doorbell 130. The battery 166, the spring contacts 140, and/or the connector 160 may each provide power to the power management module 162. The power management module 162 may have separate power rails dedicated to the battery 166, the spring contacts 140, and the connector 160. In one aspect of the present disclosure, the power management module 162 may continuously draw power from the battery 166 to power the doorbell 130, while at the same time routing power from the spring contacts 140 and/or the connector 160 to the battery 166, thereby allowing the battery 166 to maintain a substantially constant level of charge. Alternatively, the power management module 162 may continuously draw power from the spring contacts 140 and/or the connector 160 to power the doorbell 130, while only drawing from the battery 166 when the power from the spring contacts 140 and/or the connector 160 is low or insufficient. The power management module 162 may also serve as a conduit for data between the connector 160 and the microcontroller 163.

With further reference to FIG. 12, in certain embodiments the microcontroller 163 may comprise an integrated circuit including a processor core, memory, and programmable input/output peripherals. The microcontroller 163 may receive input signals, such as data and/or power, from the PIR sensors 144, the bracket PCB 149, the power management module 162, the light sensor 155, the microphone 158, and/or the communication module 164, and may perform various functions as further described below. When the microcontroller 163 is triggered by the PIR sensors 144, the microcontroller 163 may be triggered to perform one or more functions, such as those described below with reference to FIG. 14. When the light sensor 155 detects a low level of ambient light, the light sensor 155 may trigger the microcontroller 163 to enable “night vision,” as further described below. The microcontroller 163 may also act as a conduit for data communicated between various components and the communication module 164.

With further reference to FIG. 12, the communication module 164 may comprise an integrated circuit including a processor core, memory, and programmable input/output peripherals. The communication module 164 may also be configured to transmit data wirelessly to a remote network device, and may include one or more transceivers (not shown). The wireless communication may comprise one or more wireless networks, such as, without limitation, Wi-Fi, cellular, Bluetooth, and/or satellite networks. The communication module 164 may receive inputs, such as power and/or data, from the camera PCB 147, the microcontroller 163, the button 133, the reset button 159, and/or the power PCB non-volatile memory 165. When the button 133 is pressed, the communication module 164 may be triggered to perform one or more functions, such as those described below with reference to FIG. 13. When the reset button 159 is pressed, the communication module 164 may be triggered to erase any data stored at the power PCB non-volatile memory 165 and/or at the camera PCB memory 169. The communication module 164 may also act as a conduit for data communicated between various components and the microcontroller 163. The power PCB non-volatile memory 165 may comprise flash memory configured to store and/or transmit data. For example, in certain embodiments the power PCB non-volatile memory 165 may comprise serial peripheral interface (SPI) flash memory.

With further reference to FIG. 12, the camera PCB 147 may comprise components that facilitate the operation of the camera 134. For example, an imager 171 may comprise a video recording sensor and/or a camera chip. In one aspect of the present disclosure, the imager 171 may comprise a complementary metal-oxide semiconductor (CMOS) array, and may be capable of recording high definition (1080p or better) video files. A camera processor 170 may comprise an encoding and compression chip. In some embodiments, the camera processor 170 may comprise a bridge processor. The camera processor 170 may process video recorded by the imager 171 and audio recorded by the microphone 158, and may transform this data into a form suitable for wireless transfer by the communication module 164 to a network. The camera PCB memory 169 may comprise volatile memory that may be used when data is being buffered or encoded by the camera processor 170. For example, in certain embodiments the camera PCB memory 169 may comprise synchronous dynamic random access memory (SD RAM). IR LED's 168 may comprise light-emitting diodes capable of radiating infrared light. IR cut filter 167 may comprise a system that, when triggered, configures the imager 171 to see primarily infrared light as opposed to visible light. When the light sensor 155 detects a low level of ambient light (which may comprise a level that impedes the performance of the imager 171 in the visible spectrum), the IR LED's 168 may shine infrared light through the doorbell 130 enclosure out to the environment, and the IR cut filter 167 may enable the imager 171 to see this infrared light as it is reflected or refracted off of objects within the field of view of the doorbell. This process may provide the doorbell 130 with the “night vision” function mentioned above.

FIG. 13 is a flowchart illustrating one embodiment of a process according to an aspect of the present disclosure. At block B200, a visitor presses the button 133 on the doorbell 130. At block B202, the communication module 164 sends a request to a network device. Once the network device receives the request, at block B204 the network device may connect the doorbell 130 to the user's client device 114 through the user's wireless network 110 and the network 112. In block B206, the doorbell 130 may record available audio and/or video data using the camera 134, the microphone 158, and/or any other sensor available. At block B208, the audio and/or video data is transmitted to the user's client device 114. At block B210, the user may receive a notification on his or her client device 114 prompting him or her to either accept or deny. If the user denies the notification, then the process advances to block B214, where the audio and/or video data is recorded and stored at a cloud server. The session then ends at block B216 and the connection between the doorbell 130 and the user's client device 114 is terminated. If, however, the user elects to accept the notification, then at block B212 the user communicates with the visitor through the user's client device 114 while being provided audio and/or video data captured by the camera 134, the microphone 158, and/or other sensors. At the end of the call, the user may terminate the connection between the user's client device 114 and the doorbell 130 and the session ends at block B216. In some embodiments, the audio and/or video data may be recorded and stored at a cloud server (block B214) even if the user accepts the notification and communicates with the visitor through the user's client device 114.

FIG. 14 is a flowchart illustrating another embodiment of a process according to an aspect of the present disclosure. At block B300, an object may move into the field of view of one or more of the PIR sensors 144. At block B302, the PIR sensors 144 may trigger the microcontroller 163, which may then trigger the communication module 164 to send a request to a network device. At block B304, the network device may connect the doorbell 130 to the user's client device 114 through the user's wireless network 110 and the network 112. At block B306, the doorbell 130 may record available audio and/or video data using the camera 134, the microphone 158, and/or any other available sensor, and stream the data to the user's client device 114. At block B308, the user may receive a notification prompting the user to either accept or deny the notification. If the notification is accepted, then at block B310 a the live audio/video data may be displayed on the user's client device 114, thereby allowing the user surveillance from the perspective of the doorbell 130. When the user is satisfied with this function, the user may sever the connection at block B312, whereby the session ends. If, however, at block B308 the user denies the notification, or ignores the notification and a specified time interval elapses, then the connection between the doorbell 130 and the user's client device 114 is terminated and the audio/video data is recorded and stored at a cloud server at block B310 b, such that the user may view the audio/video data later at their convenience. The doorbell 130 may be configured to record for a specified period of time in the event the notification in block B308 is denied or ignored. If such a time period is set, the doorbell 130 may record data for that period of time before ceasing operation at block B312 thereby ending the session. In some embodiments, the audio and/or video data may be recorded and stored at a cloud server (block B310 b) even if the user accepts the notification and communicates with the visitor through the user's client device 114.

FIG. 15 is a flowchart illustrating another embodiment of a process according to an aspect of the present disclosure. At block B400, the user may select a “snooze time-out,” which is a time period during which the doorbell 130 may deactivate or otherwise not respond to stimuli (such as light, sound, or heat signatures) after an operation is performed, e.g. a notification is either accepted or denied/ignored. For example, the user may set a snooze time-out of 15 minutes. At block B402, an object moves into the field of view of one or more of the PIR sensors 144. At block B404, the microcontroller 163 may trigger the communication module 164 to send a request to a network device. In block B406, the network device may connect the doorbell 130 to the user's client device 114 through the user's wireless network 110 and the network 112. At block B408, audio/video data captured by the doorbell 130 may be streamed to the user's client device 114. At block B410, the user may receive a notification prompting the user to either accept or deny/ignore the request. If the request is denied or ignored, then at block B412 b audio/video data may be recorded and stored at a cloud server. After the doorbell 130 finishes recording, the objects may remain in the PIR sensor 144 field of view at block B414. In block B416, the microcontroller 163 waits for the “snooze time” to elapse, e.g. 15 minutes, before triggering the communication module 164 to submit another request to the network device. After the snooze time, e.g. 15 minutes, elapses, the process moves back to block B404 and progresses as described above. The cycle may continue like this until the user accepts the notification request at block B410. The process then moves to block B412 a, where live audio and/or video data is displayed on the user's client device 114, thereby allowing the user surveillance from the perspective of the doorbell 130. At the user's request, the connection may be severed and the session ends at block B418. At this point the user may elect for the process to revert back to block B416, whereby there may be no further response until the snooze time, e.g. 15 minutes, has elapsed from the end of the previous session, or the user may elect for the process to return to block B402 and receive a notification the next time an object is perceived by one or more of the PIR sensors 144. In some embodiments, the audio and/or video data may be recorded and stored at a cloud server (block B412 b) even if the user accepts the notification and communicates with the visitor through the user's client device 114.

As described below, some of the present embodiments advantageously locate an image sensor or a camera of the wireless A/V recording and communication doorbell behind, and/or integrate the image sensor or camera into, the doorbell button (e.g. the button used to actuate the doorbell, including sounding an audible tone and/or initiating recording of audio and/or video and/or transmitting audio and/or video). Locating the image sensor or camera behind the button, and/or integrating the image sensor or camera into the button, may conserve space within the doorbell, thereby enabling the size of the outer envelope of the doorbell to be reduced, which in turn may give the doorbell a more streamlined and visually pleasing appearance. In some embodiments in which the image sensor or the camera is integrated into the doorbell button, the image sensor or the camera may comprise the doorbell button, e.g. the image sensor or the camera may be configured such that the visitor presses the image sensor or the camera in order to actuate the doorbell (e.g. to sound an audible tone and/or initiate recording of audio and/or video and/or initiate transmitting of audio and/or video).

FIG. 16 is a front view of another embodiment of a wireless A/V recording and communication device 500 according to an aspect of the present disclosure. In the illustrated embodiment, the wireless A/V recording and communication device 500 is a doorbell. Further examples of wireless A/V recording and communication devices may be found in U.S. patent application Ser. No. 14/099,828, filed on Sep. 29, 2014, and U.S. patent application Ser. No. 62/308,746, filed on Mar. 15, 2016, the contents of which are incorporated by reference herein in their entireties as if fully set forth.

The wireless A/V recording and communication device 500 may include a housing 502, which may include but is not limited to plastic, metal, or wood. The housing 502 may serve as an exterior surface of the wireless A/V recording and communication device 500 and protect components within. In one aspect of the present disclosure, the housing 502 may be IR transmissive, so as to allow infrared light to pass through. The housing 502 may contain an aperture 503 that allows a button 504 and/or a camera 506 to protrude through. The button 504 may act as a trigger to activate the wireless A/V recording and communication device 500. When the housing 502 and the button 504 are mechanically coupled, the wireless A/V recording and communication device 500 may be sealed hermetically. The button 504 may be any optically transparent or translucent material so as to allow light to pass through to an imager 508 located behind or within the button 504. The button 504 may have convex, concave, or flat geometry, but preferably the configuration of the button 504 does not significantly distort the way in which light passes through the button 504. In one aspect of the present disclosure, the button 504 may have a tinted surface, so as to appear opaque, yet still be capable of allowing light to pass through to the inside of the housing 502. Locating the camera 506 or the imager 508 behind the button 504, and/or integrating the camera 506 or the imager 508 into the button 504, may conserve space within the doorbell 500, thereby enabling the size of the outer envelope of the doorbell 500 to be reduced, which in turn may give the doorbell 500 a more streamlined and visually pleasing appearance.

FIG. 17 is a front perspective view of the wireless A/V recording and communication doorbell of FIG. 16. The perspective view of the housing 502 in FIG. 17 illustrates the depth of the housing 502. In one aspect of the present disclosure, the housing 502, and all components within, may be mounted to a wall or an exterior surface of a structure using mechanical features (not shown) built into a rear surface 510 (FIG. 19) of the housing 502 and/or mechanical fasteners or mechanical coupling features.

Embodiments of the present wireless A/V recording and communication device 500 may include components similar to the doorbells 100, 130 described above, such as components for wirelessly transmitting audio and/or video, one or more speakers, one or more microphones, one or more antennas, one or more rechargeable batteries, and/or one or more motion sensing peripherals, such as passive infrared (PIR) sensors. In one aspect of the present disclosure, the wireless A/V recording and communication device 500 may replace a doorbell and/or an outdoor camera on the exterior surface of a home, office, or property. In this aspect, after a visitor presses the button 504 or the camera 506, the wireless A/V recording and communication device 500 may stream audio and/or video to the owner's smartphone, tablet, or computer using wireless communication protocols such as but not limited to Wi-Fi, Bluetooth, or Zigbee technology. The owner may then communicate with the visitor using a smartphone, tablet, or computer via the on-board microphones and speakers, which may be built into the wireless A/V recording and communication device 500.

FIGS. 18 and 19 are cross-sectional right side views of the wireless A/V recording and communication doorbell of FIG. 16, taken along the section line A-A in FIG. 16. FIG. 18 shows the button 504 in a static position, and FIG. 19 shows the button 504 in a depressed position. In the static position of FIG. 18, the housing 502 is cut away to show components within the wireless A/V recording and communication device 500, some of which may have been omitted for clarity. According to an aspect of the present disclosure, the button 504 may be movably mechanically coupled to the housing 502, allowing the button to travel when pressed by a human finger. After the button 504 is released, the button 504 may return to its original position. The housing 502 may contain mechanical features that secure a printed circuit board (PCB) 512 using fasteners, glue, or mechanical coupling features, for example. In one aspect of the present disclosure, the camera 506 sits behind and concentric to the button 504. The camera 506 is located on the surface of and is electrically coupled to the PCB 512. In this aspect, the button 504 may be transparent or translucent, and allows light to be directed into the camera 506 without significantly adversely affecting the images produced by the camera 506.

The camera 506 may include, or may communicate with, components integral to the operation of the camera 506, such as the imager 508 and/or a bridge processor (not shown in FIGS. 16-21, but may be similar to the microcontroller 163 described above). The imager 508 may be a video recording sensor or a camera chip, for example. In one aspect of the present disclosure, the imager 508 may include a CMOS (complementary metal-oxide-semiconductor) array, for example, and may be capable of recording high definition video files. The bridge processor may process video data recorded by the imager 508, and may transform this data into a form suitable for wireless transfer by a communication module (not shown in FIGS. 16-21, but may be similar to the communication module 164 described above).

Infrared (IR) light-emitting components, such as IR LED's 513, may be operatively connected to the PCB 512 and may be triggered to activate when a light sensor (not shown) or the camera 506 detects a low level of ambient light. When activated, the IR LED's 513 may emit infrared light out into the ambient environment. The camera 506, which may be configured to detect infrared light, may then capture the light emitted by the IR LED's 513 as it reflects off objects within the camera's 506 field of view, so that the doorbell 500 can clearly capture images at night (may be referred to as “night vision”). In the embodiment illustrated in FIGS. 18 and 19, the IR LED's 513 are located behind or within the button 504. Locating the IR LED's 513 behind or within the button 504 conserves space within the doorbell 500, thereby enabling the size of the outer envelope of the doorbell 500 to be reduced, which in turn may give the doorbell 500 a more streamlined and visually pleasing appearance.

With reference to FIG. 19, button stems 514 are protruding mechanical features designed into the button 504. When the button 504 is pressed, as shown in FIG. 19 in the direction of arrow B, the button stems 514 make contact with button actuators 516. The button actuators 516 are located on the surface of and are electrically coupled to the PCB 512. When one or more of the button actuators 516 are compressed as a result of the button 504 being pressed, the button actuators 516 may activate the camera 506 and/or other components within the wireless A/V recording and communication device 500 used to transmit audio and/or video.

FIGS. 20 and 21 are cross-sectional right side views of another embodiment of the wireless A/V recording and communication doorbell 500′ of FIG. 16, taken along the section line A-A in FIG. 16. In this alternative embodiment, the button 504 is omitted, and the camera 506 also serves as a button that a visitor may depress to activate the doorbell 500′. Omitting the button as a discrete component with respect to the camera further conserves space within the doorbell 500′, thereby enabling the size of the outer envelope of the doorbell 500′ to be reduced even further in comparison to the embodiment of the doorbell 500 of FIGS. 16-19.

Also in this alternative embodiment, a camera PCB 518 moves within the housing 502 when the camera 506 is pressed. FIG. 20 shows the camera PCB 518 in a static position, and FIG. 21 shows the camera PCB 518 in a depressed position. In the static position of FIG. 18, the housing 502 is cut away to show components within the wireless A/V recording and communication device 500, some of which may have been omitted for clarity. The housing 502 may contain mechanical features that secure the PCB 512 using fasteners, glue, or mechanical coupling features. The button actuators 516 may be located on the surface of and electrically coupled to the PCB 512. When one or more button actuators 516 are compressed, they may activate the camera 506 and/or other components within the wireless A/V recording and communication device 500 used to transmit audio and/or video.

Still referencing FIG. 20, the housing 502 may contain one or more tracking bosses 520 according to an aspect of the present disclosure. The tracking bosses 520 may be mechanical features built in to the housing 502 to help contain and guide moving components within the assembly, such as the camera PCB 518. According to one aspect of the present disclosure, the camera PCB 518 may include through-holes that receive the tracking bosses 520 to maintain the alignment of the camera PCB 518. The through-holes may comprise holes drilled through the camera PCB 518. In this aspect, the through-holes may align concentrically with the tracking bosses 520.

With reference to FIG. 21, which shows the camera PCB 518 in a depressed position, the camera 506 may be located on the surface of and electrically coupled to the camera PCB 518, according to one aspect of the present disclosure. The housing 502 may contain an aperture 522 through which the camera 506 may protrude. In this aspect of the present disclosure, the camera 506 may be used as a button that can be pressed by a user/visitor. When the camera 506 is depressed in the direction of the Arrow C, the camera PCB 518 may travel in the direction of the Arrow C, using the tracking bosses 520 to stay aligned and parallel to the PCB 512. In this aspect, when the camera PCB 518 is fully depressed, the camera PCB 518, or a part located on or within the camera PCB 518, makes contact with one or more of the button actuators 516 located on the PCB 512. When the button actuators 516 are compressed, they may activate the camera 506 and/or other components within the wireless A/V recording and communication device 500 used to transmit audio and/or video.

As described above, some of the present embodiments locate an image sensor or camera of the wireless A/V recording and communication doorbell behind, and/or integrate the image sensor or camera into, the doorbell button (e.g. the button used to actuate the doorbell, including sounding an audible tone and/or initiating recording of audio and/or video and/or initiating transmitting of audio and/or video). Locating the image sensor or camera behind the button, and/or integrating the image sensor or camera into the button, may conserve space within the doorbell, thereby enabling the size of the outer envelope of the doorbell to be reduced, which in turn may give the doorbell a more streamlined and visually pleasing appearance. In some embodiments in which the image sensor or the camera is integrated into the doorbell button, the image sensor or the camera may comprise the doorbell button, e.g. the image sensor or the camera may be configured such that the visitor presses the image sensor or the camera in order to actuate the doorbell (e.g. to sound an audible tone and/or initiate recording of audio and/or video).

FIG. 22 is a functional block diagram of a client device 800 on which the present embodiments may be implemented according to various aspects of the present disclosure. The user's client device 114 described with reference to FIG. 1 may include some or all of the components and/or functionality of the client device 800. The client device 800 may comprise, for example, a smartphone.

With reference to FIG. 22, the client device 800 includes a processor 802, a memory 804, a user interface 806, a communication module 808, and a dataport 810. These components are communicatively coupled together by an interconnect bus 812. The processor 802 may include any processor used in smartphones and/or portable computing devices, such as an ARM processor (a processor based on the RISC (reduced instruction set computer) architecture developed by Advanced RISC Machines (ARM).). In some embodiments, the processor 802 may include one or more other processors, such as one or more conventional microprocessors, and/or one or more supplementary co-processors, such as math co-processors.

The memory 804 may include both operating memory, such as random access memory (RAM), as well as data storage, such as read-only memory (ROM), hard drives, flash memory, or any other suitable memory/storage element. The memory 804 may include removable memory elements, such as a CompactFlash card, a MultiMediaCard (MMC), and/or a Secure Digital (SD) card. In some embodiments, the memory 804 may comprise a combination of magnetic, optical, and/or semiconductor memory, and may include, for example, RAM, ROM, flash drive, and/or a hard disk or drive. The processor 802 and the memory 804 each may be, for example, located entirely within a single device, or may be connected to each other by a communication medium, such as a USB port, a serial port cable, a coaxial cable, an Ethernet-type cable, a telephone line, a radio frequency transceiver, or other similar wireless or wired medium or combination of the foregoing.
